Whats to cold, for seed sprouting?

[MedResearcher]

Just started germinating a few seeds. Our greenhouse has been having nights down to 37-39 degrees, but the days get quite warm, up to 90.

It sort of feels like it would be a bit to cold to put the seeds out in it. Was hoping to get a few opinions, if it would be ok, or a bit to cold?

Could set them up indoors under a light bar, although I would rather not if possible. I like the idea of them sprouting under the sun, and not having to adapt from artificial light to the sun.

Thanks,

50's is cold, you might lose beans from rot. At $10 a seed I'd start inside or wait.

I would germinate them indoors at constant temperature 78-82*F, so that they surely sprout.
Otherwise you risk them germinating one by one, when each seed "feels like" doing it. It depends a lot on genetics - different strains are adapted to different climates and have different strategies measuring when it's "best" to sprout. All seeds seems to be triggered when temperature is above 78*F for a longer period of time.
Good luck!

It will work, if you are growing Siberian hemp
